"i'm so sick of this crap, it's over, it's been 140 yrs, get over it. no one was personally involved w/ it so lets move (o)n."
Here's how I interpret this post - dismissing an attempt to acknowledge the harm that came from slavery and from unfair laws like Jim Crow. If you don't see this as a dismissal, then we're using a different system of processing information.
I don't personally care if you think any apologies for Jim Crow and the like are BS. I don't expect anything different. But I do think it is comical and naive.
